The claim is directed to the collective appearance of a locking system for a flat bed trailer. The separate pieces of the design have been shown for clarity, however the design is directed to the entire article as shown in FIG. 1 and FIG. 4.

In the drawings, the broken line in FIGS. 1-6 depict portions of a trailer and form no part of the claimed design. 

We claim the ornamental design for a locking system for a flat bed trailer, as shown and described.
